IMHO it is indicative to some point. Bernal was superior to Remco on every single climb so far and I think it's quite unlikely to be different on longer ones. Actually Bernal's advantage should be even more exposed
In the longer mountaintop finish that we had until today Remco was able to follow Bernal so I don't think that Bernal will have that big advantage in the longer mountains unless Evenepoel suffers with the gradients or altitude.
